Already have the iPhone 5?

All you do ask for directions like you normally would, but tack on "via transit." So, for example, to find the nearest Starbucks, you'd say, "Take me to the nearest Starbucks via transit."

What happens next is that Siri pulls up a list of any installed "routing apps" -- including Google Maps, which, as you probably know, recently returned to the iPhone. (You'll also see a list of options available from the App Store.) From there you tap Route, and presto: you've got directions via Google Maps.

This is perhaps better shown than explained, so check out JailbreakNation's quick video:

Granted, this isn't perfect. There's still that intermediate step of the Routing Apps list and having to tap Route. So it's not a fully voice-powered way to access Google Maps.

What do you think of this clever little hack? Will you use it? Or do you think critics have been too hard on Apple Maps, and that for the most part it works just fine, thank you? Let's hear from you in the comments.
